How it works

Three steps.
Then it just runs.

No prompts to write. No templates to fill in. Signate learns from what you've already sent.

Step 01

Connect Gmail

One OAuth click gives Signate read and send access. Your credentials are encrypted and you can revoke access anytime from your Google account settings.

Connected: jay@gmail.com ● Active
Step 02

Build your voice

Signate analyzes up to 80 of your sent emails — extracting your tone, formality, greeting style, sign-off patterns, and the quirks that make your writing recognizably yours.

Step 03

Handle the inbox

New emails are triaged, classified by sender type, and drafted. High-confidence replies go out automatically. Everything else lands in your queue — draft ready, one click to send.

Before & after

Your inbox, transformed.

Most people spend 2–3 hours on email every day. Signate gives that time back without losing the personal touch.

✗  Without Signate

Buried in your inbox

Every reply is a decision. Every follow-up falls on you. Your most important emails often get the least attention because you're exhausted by volume.

  • 2–3 hours daily just on email
  • Leads go cold while you're in meetings
  • Clients wait days for simple replies
  • Follow-ups fall through the cracks
  • Important emails buried in noise
✓  With Signate

Inbox handled, voice intact

Routine emails go out automatically. Complex ones are drafted and ready for your approval. You're back to handling the 20% that actually needs you.

  • ~8 minutes a day in your review queue
  • Leads get same-day replies, in your voice
  • Clients feel heard without extra effort
  • Escalations flagged before they become fires
  • Full audit log of everything sent
Features

Not a template engine.
An actual voice model.

Most email AI sounds like email AI. Signate sounds like you — because it learned from you specifically.

🎙

Deep voice profiling

Signate extracts your formality level, average reply length, punctuation style, greeting patterns, and signature phrases. Every draft it writes reflects all of them — not a generic AI tone.

🧠

Sender intelligence

Every inbound email is classified by relationship. Signate adjusts tone based on who's writing, not just what they said.

Lead Client Investor General

Auto-send or review

High-confidence replies go out immediately. Everything uncertain hits your queue — draft ready, one click to approve.

🚨

Escalation detection

Signate recognizes legal language, frustrated clients, and high-stakes requests — and flags them for personal attention instead of guessing.

This email references contract terms and mentions legal review. Escalated — no reply drafted.
📋

Full audit log

Every send, edit, rejection, and escalation is timestamped. You always know exactly what Signate did.

🔒

Private by design

Your emails are processed in memory to build your voice model — not stored long-term. OAuth tokens are encrypted at rest and scoped only to what Signate needs to do its job. You can revoke access in one click.

Who it's for

Built for people
email is already taking from.

If you're good at your job, your inbox grows faster than you can handle. Signate is for the people who can't afford to fall behind.

My EA read through a week of replies and couldn't tell which ones I'd written. Genuinely unsettling — in the best way possible.

200+ emails a day. Signate handles maybe 70% automatically. That's three hours back every single day. The escalation alerts alone have saved me twice.

The review queue is the part I didn't know I needed. Eight minutes in the morning and I'm done with email for the day. It's wild.

I was skeptical about the "voice matching" claim. After two weeks I had investors asking if I'd hired an EA. I hadn't. It was Signate.

Setup took nine minutes. By the afternoon Signate had already handled six emails. All six were spot on. Didn't touch one of them.

The escalation system is worth the subscription price alone. It caught a contract dispute on a Friday afternoon that I would have missed until Monday.

I run a 12-person consulting shop. We put Signate on my account first, then rolled it out to the whole leadership team. Night and day difference.

My close rate actually went up after using Signate because leads were getting replies within the hour instead of waiting two days for me to surface them.

FAQ

Questions we actually get.

How does Signate learn my writing voice? +
Signate analyzes up to 80 of your most recent sent emails using Claude AI. It extracts patterns in your formality level, sentence length, greeting and sign-off phrases, punctuation habits, and tone shifts depending on who you're writing to. The result is a personalized voice profile that's used to generate every reply.
Is my email data stored? +
Your emails are processed in memory to build your voice profile — they are not stored in our database long-term. The voice profile itself (a structured description of your writing style) is stored, not the raw email content. Your Gmail OAuth token is stored encrypted and scoped only to the access Signate needs.
Can I review replies before they're sent? +
Yes — always. Signate's confidence threshold determines whether a reply goes out automatically or lands in your review queue for approval. You can adjust this threshold, and any email type or sender can be configured to always require your sign-off. You can also edit any draft before approving it.
What happens when Signate isn't sure how to reply? +
If the reply confidence is below your threshold, the email goes into your review queue with a draft ready for your approval. If Signate detects escalation triggers — legal language, urgency, frustrated tone — it flags the email for personal attention instead of drafting a reply at all.
Does it work with Google Workspace? +
Yes. Signate connects via standard Gmail OAuth and works with both personal Gmail accounts and Google Workspace (formerly G Suite) accounts. Any account accessible through Gmail's API is supported.
Can I pause or disable Signate temporarily? +
Yes. You can disconnect Gmail from your settings at any time, which immediately stops Signate from accessing your inbox. Your voice profile is preserved, so reconnecting picks up right where you left off. You can also adjust your auto-send settings to require manual approval for everything.
How long does setup take? +
Most users are up and running in under 10 minutes. Connecting Gmail takes about 30 seconds. Building your voice profile takes another 2–3 minutes. After that Signate starts monitoring your inbox immediately — your first auto-reply can happen within the hour.

Stop drowning
in your inbox.

Connect Gmail, build your profile, and let Signate handle the rest — in under ten minutes.
